Bell’s inequalities, superquantum correlations, and string theory. (English) Zbl 1234.81031
Summary: We offer an interpretation of superquantum correlations in terms of a “doubly” quantum theory. We argue that string theory, viewed as a quantum theory with two deformation parameters, the string tension \(\alpha^{\prime}\) , and the string coupling constant \({\mathfrak g}_{S'}\), is such a superquantum theory that transgresses the usual quantum violations of Bell’s inequalities. We also discuss the \(\hbar\rightarrow \infty \) limit of quantum mechanics in this context. As a superquantum theory, string theory should display distinct experimentally observable supercorrelations of entangled stringy states.
